Jumping on the band wagon
If you are talking specifically about the nuclear plants, how much of a disaster is it? We don't know yet. Fear mongering speculators will say it's horrific, more calm and less pant wetting types will say it's bugger all. As far as the world is aware so far no one has died of radiation poisoning, the only people to die at the plant have been caught in explosions.
I also love how all the countries are talking about seeing if their nuke plants could withstand an earthquake like that when Fukushima sustained very little damage from the earthquake. What caused all the problems was the huge tsunami which came in.
It really doesn't help with the US saying it's all going to blow up and everyone should run for miles when their people know less about what is going on at the plant than the Japanese government. Damn fear mongering yanks, If one of your nuke plants went up like this you would just abandon it and let it melt down.
